S-5-NH 1.5 Brochure

Reversible Hinge Design Ensures Proper Fit on Wide and Medium-Width Profiles

Designed specifically for 1-1/2” nail strip profiles with a wider horizontal dimension (> 0.475” and ≤ 0.800”), the S-5-NH 1.5 (“NH” stands for nail strip hinge) is an ideal mounting solution for VicWest Prestige, NewTech FF150 and similarly dimensioned profiles.

The innovative insert is a “hinge” design and features a toe to engage the female portion of the panel. It forms to the shape of the seam, preventing damage at the point of attachment, while offering you optimal holding strength. The hinge insert is also reversible to allow for proper fit on both wide and medium-width profiles.

For ease of installation, the T-30 Torx setscrews are angled upward to facilitate tool insertion. The hinged insert is also staked at one end to facilitate installation.

Minis Available

The NH 1.5 Mini clamp is a more economical solution for lighter-duty attachments where Herculean holding strength is not required. 

All standard and Mini clamps undergo rigorous load testing. Negative load normal-to-seam testing (pull-up) is performed on all Mini clamps, and parallel-to-seam testing (drag load) is performed on all standard clamps.

For nail strip profiles with 1” seam height, see S-5-N.” See also the S-5-N 1.5 for nail flange metal roof profiles with a seam base dimension ≤ .50” (12.7 mm).

Does the S-5-NH 1.5 Fit Your Roof Profile?

How to Install the S-5-NH 1.5 Clamp on Your Roof Profile*

Slide insert into clamp and place over seam at the desired location. Tighten setscrew in clamp, pushing the insert against the side of the seam, opposite the open edge of the female portion.

Ensure the “toe” on the clamp body sits below the open edge of the seam. The insert will form to the shape of the seam as the setscrew is tensioned. Attach ancillaries using the top M8 bolt hole.

*See more detailed installation instructions in the PDF download below.

*S-5! clamps may be moved in the event of initial misplacement. However, due to the ensuing oxidation process which acts as a natural thread lock, we can express no opinion to the performance of a clamp once it has been removed and reinstalled or the ability to remove the clamp after this process has occurred.
